FOREIGN DEPARTMENT. 

HOWSONS' PATENT OFFICES. 

PHILADELPHIA. 



While the manufacturing countries of Europe are profit- 
able fields for the working of really useful inventions, 
great caution should be exercised by American inventors 
in securing Foreign Patents. 

Presuming an invention to be valuable, there are two 
essentials to a successful and profitable result from For- 
eign Patents obtained for it. 

The first is that the papers be sent from this Country, 
in such shape as to secure the best possible Patents, and 
the second is to employ, abroad, experienced Agents of 
reliability and good standing, to obtain the Patents. 

As to the first essential, the preparation of the neces- 
sary papers, it may be remarked that there are many 
popular errors as to the requirements of the difierent 
Countries wherein Patents are sought. As an instance of 
these errors may be cited the general delusion, not con- 
fined to inventors, but entertained by too many Agents in 
this Country, that in applying for British Patents, it is 
merely necessary for the inventor, or his Agent to send a 
copy of the American Patent. The possible evil results of 



4 

such a course will be understood when it is borne in mind 
that the specifications of English and other Foreign Patents 
are or should be very different documents from those re- 
quired in this Country, and that an invention with a va- 
riety of modifications which would require separate United 
States Patents, can be included in one English Patent, if 
the title and specification be carefully prepared by one ex- 
perienced in such matters. 

Great numbers of English Patents for American inven- 
tions are granted on the most reckless papers, because 
there are practitioners in this Country who induce their 
clients to believe that a copy of an American Patent is all 
that is necessary to send to England, and because there 
are Agents there who follow suit and grind out Patents 
by wholesale at cheap rates, regardless of their scope and 
validity. The American owner of the English Patent 
does not discover his mistake until there is an opening 
for a profitable negotiation of his Patent, when the latter 
is submitted to the scrutiny of a competent authority, 
and its true character is developed. 

As to the second essential, the selection of a reliable 
Agent abroad to look to the interests of the American 
inventor, it should be borne in mind, that the profession 
of a Patent Solicitor in England, is open to all. In this 
Country positive dishonesty on the part of a Patent Solici- 
tor is punishable by suspension from practice, and the pa- 
pers of an incompetent or reckless man are subjected to 
the close scrutiny of examiners, and his low standing be- 



comes apparent to the Patent Office, though unfortunately 
not to the public, perhaps, in sufficient time to prevent 
his doing serious damage to inventors. But even these 
restrictions, insufficient as they are, are totally vranting 
in English practice, where any impostor can dub himself a 
Patent Solicitor, present any sort of papers and deceive 
his clients with impunity. The results of all this have 
been so disastrous to inventors, that the evil has attract- 
ed the attention of the Government and it has been pro- 
posed before a Committee of the House of Commons, to 
permit no one to practice as a Patent Solicitor until he 
has passed a rigid examination and has presented proof 
of good character, a plan which might be adopted in this 
Country with beneficial results to inventors. Curiously 
enough, the salutary proposition was opposed before the 
House of Commons Committee, by one wholesale practi- 
tioner, on the ground that such a law might drive many 
from the profession. 

The only remedy which an American inventor has 
against such evils, is to avoid the flattering inducements 
held out by cheap practitioners, and to determine that his 
Foreign Patent shall be obtained through a man of the 
highest standing and well tried ability. Men of this class 
can always command substantial fees, but never ask for 
more than their services ax^e worth. 

Since the establishment of these offices twenty years 
ago, we have invariably adhered to the rule of employing 
none but gentlemen of the highest professional standing 



to represent us abroad, preferring to pay the fees which 
the value of their services can command, to running such 
risks as are foreshadowed in the lower charges of men of 
lower standing. 

Our principal correspondent in London, is J. H. John- 
son, Esq., of 47 Lincoln's- Inn- Fields, the well known au- 
thor of the *^ Patentee's Manual," and a gentleman 
having extensive practice in Patent cases before the Eng- 
lish Courts. Our correspondent for Continental Europe, 
is the house of Armengaud Aine, of 45 Kue St. Sebas- 
tien, Paris, a name rendered familiar in this Country, by 
most valuable engineering and mechanical publications. 

We have corresponded with these houses for well nigh 
twenty years, and we know that any Patent obtained 
through them possesses a status which can be imparled by 
very few others in their respective Countries. 

The procuring of Foreign Patents has long been a lead- 
ing branch of our business, and one for the prosecution of 
which we may fairly claim to have peculiar advantages. 
The extent of this branch of our business has been for 
several years second to none in this Country, and as our 
senior partner has practised as a Patent Solicitor abroad, 
inventors may be satisfied that their Foreign Papers will 
be well prepared. 

There are such hosts of Patent Circulars, however, con- 
taining loud-sounding professions, that we feel it incum- 
bent upon us not to content ourselves with simple asser- 
tions, but to comply with the reasonable demands of 



inventors for proof of capacity, &c., and therefore we 
direct the attention of our readers to the names (published 
at the close of this pamphlet) of parties for whom we have 
acted in Patent business. 

In the folio wing pages will be found particulars relating 
to Patents in different Countries, with estimate of the cost 
in United States currency. These particulars are neces- 
sarily brief, but will suffice to point out the leading fea- 
tures of the laws of different countries. 

It should be understood that the estimates given 
signify the cost in United States Cur7'ency and in- 
clude all Government fees and agency fees, both 
here and abroad, as well as the cost of specifications, 
drawings, translations, mail and express charges 
and everything neoessarj^ to complete the Patent. 



8 
GREAT BRITAIN. 

Letters Patent cover England, Wales, Scotland, Ireland, 
and the Channel Islands, but not the Colonies, most of 
which grant separate Patents under laws of their own. 

Tey^m of British Patents : Maximum, 14 years ; but if 
the invention has been previously patented in other coun- 
tries the British Patent will not be valid after the expira- 
tion of any such previous Foreign Patent. 

Cost of obtaining — from |300 to $340, payable in ad- 
vance ; or if preferred, |120 may be paid in advance, and 
the balance, |180 to $220, within three and a-half months. 

N. B. — Payment of the entire fees at once secures 
greater expedition in the completion of the Patent, an 
important point, since it would appear from recent rulings 
that in the case of conflicting claims, priority in law will 
be adjudged to the Patentee who first secures the seal. 

KoTE. — A stamp duty of £50 is payable before the end 
of the third year of the Patent, and a further duty of 
of £100 before the end of the seventh year* If either of 
these duties be not paid in time, the Patent is irrevoca- 
bly lost. 



FRANCE. 

Term of Patents : Maximum, 15 years ; but can in no 
case extend beyond the term of an original Foreign Pat- 
ent for the same invention. 

.Cost — including Government Tax for first year, $100 to 
$120. 



9 

Note. (1.) An annual tax of about $20 gold must be paid. 

(2.) The invention must be worked in France within 
two years, and operation must not afterwards be discon- 
tinued for two successive years. 

(3.) To effect a registered assignment of a patent the 
tax for the remainder of tlie years during which the patent 
has to run at the moment of the transfer, must be paid 
into the Treasury. 



ALSACE-LORRAINE. 

In this District, formerly part of France, but detached 
by the events of the late war, separate Patents are now 
granted upon terms and conditions substantially similar 
to those governing French Patents. 

Cost — -The same as for France. 



BELGIUM. 

Term of Patents : Maximum, 20 years ; but in the case 
of inventions previously patented elsewhere, the Belgian 
Patent will expire at the same time with the original 
Foreign Patent. 

Cost — including Government Tax for first year, |90 to 
$110. 

Note. (1.) Annual tax to be paid, amounting for the 
second year to about $4 (gold, ) and increasing annually 
thereafter, at the rate of about $2 (gold) per annum to the 
end of the term. 



10 

(2.) The invention must be worked in Belgium within 
one year after putting into operation abroad. 



We have grouped England, France, and Belgium to- 
gether, as the Foreign Countries, in which as a rule Pat- 
ent property is most available and valuable. These 
being contiguous manufacturing countries, a patent in one 
of them is likely to be made more secure and consequently 
more valuable by patents in the others. No doubt, how- 
ever,, there are numerous inventions of general utility, or 
specially adapted to the wants, or peculiar characteris- 
tics and capacities of some or other of the Patent-grant- 
ing Countries hereinafter referred to, and w^hich, there- 
fore, might in such countries, become by proper care and 
attention sources of profit to the inventors. 



GERMANY. 

Under this head we include 

1. Prussia. Including Hanover, Hesse Cassel, Nassau, 
Holstein. 

2. Bavaria. 

3. Baden. 

4. Saxony. 

5. Wurtemburg. 



11 

6. Various Grand Duchies, Duchies, Principalities, and 
Free Cities, as follows : 

Anhalt, Waldeck, 

Hesse Darmstadt, Brunswick, 

Keuss Greitz, Lippe Detmold, 

'^ Schleitz, ** Schaumbourg, 

Saxe Altenbourg, Oldenburg, 

*' Cobourg, Bremen, 

'' Meiningen, Luheck, 

** Weimar, Homburg, 

Schwarzbourg Rudolstadt, Mecklenburg Strelitz, 

" Sondershausen, •* Schwerin. 

]Sr. B. The States and Cities italicised seldom grant 
Patents. 



(t) PRUSSIA. 

Term of Patents: Maximum, 15 years; fixed by Gov- 
ernment, and generally limited to 5 years, without exten- 
sion. 

Cost— %\00 to $120. 

Note. — The invention must be operated in Prussia, 
within a limit of time fixed by Government, varying from 
6 months to a year, generally the latter. 

]Sr. B. — In Prussia, Patents are more generally refused 
than granted to foreigners, and the law and its admin- 
istration are very vexatious. 



12 

(2.) BAVARIA- 

Term: Maximum, 15 years; but camiot exceed that 
of a previous Foreign Patent. Patents obtained in the 
first place for shorter terms may be prolonged. 

Cost — $160 to $175 for two years term, and increasing

Note. — The invention must be in operation, in Bavaria, 
vrithin 3 years, if the Patent he for more tlian six years^ 
but for Patents of less than six years, operation must be 
within the first half of the term. 

In the case of a two year Patent, therefore, the Pat- 
entee has one year for operation.

Term of Patents : Maximum, 10 years ; but a shorter 
term may be asked for, with the privilege of extension. 

Cost—iov 3 years patent, $150 to $175. 

Note. — The invention must be worked in AYurtemburg 
within 2 years, and must not afterwards be discontinued 
for two years consecutively.

(saving in those italicised), Patents may be obtained. 

Term : 5 to 10 years, as fixed by the Government . 

Cost— $115 to $140, each State. 

Note. — One year is generally allowed for working the 
invention. 



AUSTRIA.

$150. 

Note. — (1) To maintain the Patent from year to year, 
Government and municipal taxes must be paid, amount-

CERTIFICATES 



Burlington, Iowa, Oct, 2, 1857. 
Dear Sir : — I take this occasion to state to you, that 
for several years past I have been acquainted with the 
manner in which you have conducted your business as a 
Patent Solicitor. This has always been highly creditable 
to yourself and satisfactory to the Patent Office. You 
understood your cases well, and presented them in that 
intelligible form which generally insured success. I for- 
ward this certificate, hoping that it may be serviceable to 
you in continuing to find that employment in your profes- 
sion, to which your intelligence, industry and courteous 
bearing so justly entitle you. 

Yours, very truly, 

CHARLES MASON, 
Henry Howson, Esq. Late Commissioner of Patents, 



■:o: 



National Association of Wool Manufacturers, ) 

55 Summer St., Boston, Mass., Oct. 6, 1865. ^ 

My Dear Sir : — It gives me great pleasure to give my 

testimony as to the manner in which you have conducted 

your business as a Solicitor of Patents, during the four 



18 

years that I was Chief Clerk and Executive Officer of the 
XJ. S. Patent Office, and for a considerable period Acting 
Commissioner. 

During that time your business at the Patent Office was 
surpassed in extent by but one firm in New York. The 
papers presented by you, specifications, drawings, corres- 
pondence, &c., were invariably models of neatness, accu- 
racy and legal precision. They were frequently pointed 
out to younger solicitors as among the best examples and 
precedents for practice in the Office. Your intercourse 
with the Office was so conducted that all the rights of your 
clients were secured without personal controversy. With 
the best opportunities for judging, I do not hesitate to say 
that your thorough knowledge of mechanics and patent 
law places you in the first rank of Solicitors of Patents in 
the United States. 

Very truly, yours, 

JOHN L. HAYES, 

Late Chief Clerk and Executive Officer U. S. Patent Office, 
H. HowsoN, Esq., Philadelpliia, Pa. 



:o:- 



WasMngton, D, C, A^ov. 20th, 1865. 
I fully and cheerfully endorse the statement made by 
Mr. Hayes in the above letter, and commend Mr. HowsoN 
to the i>atronage of the inventors of the country. 

D. P. HOLLOW AY, 
Late Commissioner of Patents. 



19 

Cincinnati, Xov. l%th, 1871. 
Gentlemen : — I take great pleasure in testifying to the 
ability and promptness witli which you conducted your 
business before the Patent Office while I was Commis- 
sioner. Your cases were thoroughly, accurately and neat- 
ly prepared, well presented and strongly urged. I wish 
you every success in your business. 

Very truly, yours, 

S. S. FISHEB.
